Performance Analysis of Hybrid Filter with HUA Optimization based PI-SRF Control Technique for Power Quality and Reactive Power Management

Abstract

This paper proposes a new Human urbanization algorithm (HUA) tuned Proportional-Integral (PI)-Synchronous reference frame (SRF) method for the control of hybrid filter. Hybrid filter is a custom power device that takes care of harmonic and unbalancing related power quality issues along with reactive power compensation, without burdening the design rating of active filter components like inverter and its switches. The performance of hybrid filter heavily depends on its control design, which in turn, relies on the controller design parameters, such as the PI controller. The performance of SRF method relies heavily on PI controller. The proposed HUA based optimization for PI offers better control and response, when compared with other popular methods. Moreover, the SRF method for controlling the active filter component of hybrid filter offers flexibility to support a controlled amount of reactive power depending on its rating. The hybrid filter system comprises of a four-leg shunt active filter and a shunt passive filter, to provide harmonic, neutral current and reactive power compensation. A complete simulation performance analysis is presented for the proposed HUA tuned PI-SRF based hybrid filter using MATLAB/SIMULINK. Also, a comparative analysis is performed for different tuning methods of PI controller.
